Risk group | Treadmill score | Average annual cardiac mortality, % |
|---|
Low | ≥ 5 | 0.25-0.50 |
Moderate | −10 to < 5 | 1.25-2.0 |
High | ≤ −11 | 5.0-7.0 |
- aDuke formula: treadmill score = (exercise duration in minutes) – (5 × ST-segment deviation in millimeters) – (4 × treadmill angina index), where the treadmill angina index = 0 for no exercise angina, 1 for exercise angina and 2 for exercise-limiting angina
